11 Claims.

This invention relates to new and useful improvements in Sprayers, and fluid containers therefor.

One object of the invention is to provide an improved sprayer which is particularly adapted for use in spraying insecticide or other fluid and which is simple in construction and economical in manufacture.

An important object of the invention is to provide an improved sprayer wherein the fluid container is entirely separate from the sprayer barrel, said container being constructed so as to be readily attached to the barrel, whereby the-container may be purchased separately and then combined with the barrel inform the complete sprayer; said container being adapted for use with any type of sprayer, either the siphon type or the pressure type.

A particular object of the invention is to providean improved liquid container for insecticide, or other fluid, which has said insecticide sealed therein, whereby a tamper-proof Container is offered for sale to the buying public; said container being so constructed that it may be readily connected to an ordinary fluid sprayer barrel,

whereby the same container in which the insecticide, or other fluid, is offered for sale may be utilized as the fluid container of the sprayer.

Another object of the invention is to provide an improved liquid container, of the, character described, wherein the means, by which the sprayer barrel is connected to the container, is disposed within said container, whereby the outer surface of the container is substantially smooth, which'makes it possible to fill and seal said container with the present automatic'equipment now in general use for this purpose. A further object of the invention is to provide an improved container, for use with a-sprayer barrel, having an opening which is normally sealed by a frangible closure, whereby the container reaches the consumer in a sealed condition, the frangible closure being arranged to be ruptured when the sprayer barrel is connected therewith so -'as to permit access to the contents of said container; the container being preferably constructed of a relatively'chea'p material'so that it may be discarded after its contents are used, and a new, full container substituted for the same, thereby obviating the necessity of employing a single liquid receptacle "for the sprayer and refilling such receptacle from time to time.

Still another object'of the invention is topr'ovide an improved non-refillable container adapted to be connected to-a sprayer barrel and having a positive seal at the point of its connection with the barrel; the provision or the non-refillable container making it necessary to substi tute a new container each time a container is emptied and thereby assuring 'a new seal upon each replacement, whereby leakage is substantially eliminated and more eflicien-t operation of the sprayer is effected.

A "sti llfurther object of the invention is to provide a fluid container, of the character described, wherein the contour of the container is utilized to co-act with the connecting means between the sprayer barrel and container "so as to assure a tight connection between the parts.

A particular object of the invention is to provide an improved sprayer, of the character described, wherein the sealing means is so arranged that any pressure within the container, when the container is attached to the sprayer barrel, will tend to increase the seal between the parts to prevent any leakage at the point of attachment.

A construction-designed to carry out theinvention will he hereinafter described, together with other featuresof the invention.

The invention willbe more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example-of the invention is shown, and

wherein:

Figure 6 isa view, partly in section and partly in elevation, illustrating the barrel attached to thecon'tainer,

Figure -'7 is a horizontal, cross-sectional view, taken=on the line l -l of Figure 6,

Figures is a partial plan view of another form of container, and

Figure 9 is an enlarged-transverse, vertica1,sectional view'of this form of the invention.

in the drawings, the numeral l0 designates a cylindrical container, can or receptacle which is constr-uoted -=o f tin, or other suitable material,

The container is made in the usual manner and includes the cylindrical wall H which is of one piece of material and which has the circular ends l2 crimped, or otherwise secured thereto. The container may be of any desired size so as to have the desired fluid content.

In carrying out the invention, an opening I3 is formed in the wall of the container, being preferably disposed midway between the ends I2 (Figure 4) and this opening is substantially circular in shape. A pair of diametrically opposed recesses I i, which are substantially semi-circular in shape are provided at the marginal portion of the circular recess and these recesses are disposed in a plane parallel to the longitudinal axis of the container. Manifestly, since the opening 13 and recesses M are formed in the curved wall of the container, said opening and recesses are curved, relative to a horizontal plane, as is clearly shown in Figure 5. However, the recesses, being disposedin alinement with the longitudinal axis of the container and being of a narrower width than the circular opening, do not have as much curvature transversely thereof as does the opening. Due to its size, the margins of the opening l3 which are located in a plane at a right angle to the longitudinal axis of the container are below the centralportion of said opening in a horizontal plane, as is illustrated in Figure 5.

A cylindrical body or member [5, which has the form of an inverted cap, is located within the container below the opening l3 and this member includes a base plate or bottom [6 provided with an upstanding annular flange IT. The upper end of the flange I! is soldered, or otherwise secured, to the. inside wall of the container immediately beneath said opening and the diameter of said member is sufficient to encircle the recesses I4, as well as said opening (Figure 4). 16 of the member is provided with an axial opening I8 which is normally sealed by a frangible closure disk [9. Manifestly, the bottom of the member I is spaced from the opening I3 and also from the inner wall of the container and, thus, an internal chamber A is formed below the opening. An annular sealing gasket or ring 20 may be placed within this chamber, said gasket being positionedwithin the member l5 prior to its attachment to the container. However, in some cases, the gasket may not be necessary and could be omitted.

' The member [5, as well as the opening is and recesses l4, are utilized to connect the container or can In to a sprayer barrel, as will be hereinafter explained. It is noted that the member is disposed within the container and takes" up a relatively small amount of the internal area thereof, whereby it does not materially reduce the fluid content of said container. By disposing the member within the interior of the container, the outer surface thereof remains smooth and no projections are formed on such surface. Therefore, the container has an exterior construction which is exactly the same as the usual containers or cans which are now in general use for containing motor oil, canned foods and the like, and said container may be filled and sealed with the present type of automatic filling and sealing equipment which is now in use. No special equipment is required. The container may be filled with insecticideor other fluid to be sprayed.

The sprayer barrel 2|, to which the container or can is to be connected, has been illustrated The bottom all as the pressure type, such as is described'in my 6 Patent No. 1,957,345, issued May a, 1934, but it is pointed out that any suitable sprayer barrel may be used. The barrel has the usual piston 22 reciprocable therein and this piston is actuated by the piston rod 23 which is provided with the handle 24. The forward end of the barrel has a nozzle head 25 secured thereto, said head being separated from the interior of the barrel by a disk 26 which is provided with a valved opening 21. An angular eduction tube 28 is mountedwithin the head and extends from the discharge opening 29 in the nozzle head downwardly through a collar 30 which is formed integral with the underside of the head 25 and which depends therefrom. The lower end of the tube projects a substantial distance below the collar.

The collar 30 has a diameter which is substantially equal to the diameter of the circular opening [3 in the Wall of the container l0, whereby said collar is insertable therein. A pair of diametrically opposed, radially-extending lugs 3| are preferably for'med integral with the collar and said lugs extend in a plane parallel to the longitudinal axis of the nozzle head 25 and sprayer barrel 2|.

In attaching the sprayer barrel to the container or can, the frangible closure disk I9, which closes the opening l8, in the bottom of the member I5, is punctured or ruptured by any suitable means, it being possible to employ the lower end of the eduction tube 28 for this purpose. The tube is then introduced through the punctured disk and is lowered until the collar 30 enters the circular opening l3 in the-wall of the container. The sprayer barrel and nozzle head are then rotated to aline the radial lugs 3| on the collar with the recesses [4 which are located at the marginal portion of the circular opening I3. Due to the disposition of the recesses, as well as the location of the lugs 3|,it is necessary to aline the longi tudinal axis of the barrel with the longitudinal axis of the container in order to bring the lugs into registration with the recesses. After said lugs are alined with the recesses, further downward movement of the sprayer barrel may continue until the lower end of the collar 30 strikes the gasket 20 within the chamber A. At this time, the upper surfaces of the lugs 3| are within the chamber immediately below the inner wall thereof. Upon rotation of the barrel 2| to move said barrel to the position shown in Figure 1, the lugs 3! are moved out of alinement with the recesses l4 and are engaged with the inner wall of the container beneath the marginal portion surrounding the circular opening 13, as is clearly shown in Figure 1. Due to the curved inner surface of the container co-acting with the straight lugs 31, acam action is had which serves to draw the collar 30 into tight engagement with the packing gasket. Also, a tight frictional hold between the lugs and container is set up, whereby the connection between these parts is positively maintained,

Obviously, when the container and sprayer barrel are connected as above described, a complete sprayer is had. Operation of the piston 22 willbuild up a pressure in the nozzle head and upper endof the container and fluid from the container will be drawn into the eduction tube and ejected through the outlet opening 29 in the nozzle head. Any drainage of fluid from the nozzle head will, of course, pass downwardly through the collar and then back into the container. It is noted that the pressure which is built up in the container will act against the underside of the bottom l6 and, since this area is greater than the area above said bottom which is exposed to the same pressure, the bottom is urged upwardly against the end of the collar to aid in assuring a fluid-tight seal between the collar and gasket. When the container is emptied, it is discarded and a new one substituted therefor. By providing this type of container, the liquid insecticide, or other fluid, may be sealed in said container, which is tamper-proof and offered for sale to the consumer. After purchase, the consumer may readily attach the container to the sprayer barrel and dispense the contents as desired. Thus, the same container which is employed for selling the fluid is utilized as the liquid receptacle for the sprayer. Since each container has a sealing gasket incorporated therein, it is manifest that each time a container is emptied and a new one substituted therefor, a new seal is provided. This assures a fluid-tight seal at the connection between the container and sprayer barrel at all times.

In some instances, and particularly where a pressure type sprayer barrel is not employed, it might be desirable to construct the container in the manner shown in Figures 8 and 9. In such case, the wall of the container I is provided with an oval shaped opening 50 which is normally sealed by a frangible disk which is secured to the inner wall of the container beneath the opening. The sprayer barrel is provided with a collar 52 having lugs 53 thereon and said lugs and collar are insertable through the opening 50, as will be readily understood. Above the lugs an annular flange 54 is provided on the collar and, when said lugs are rotated to engage the underside ofthe container, as shown in Figure 9, the flange is spaced from the outer surface of the said container. I

A suitable packing gasket 55 surrounds the collar 52 and is clamped between the outer surface of the container and the flange 54 so as to seal the opening. Manifestly, this is a much simpler form of the invention and is preferably employed with sprayers, other than the pressure type. However, it might be possible to clamp the gasket 55 sufficiently tight beneath the flange to resist a leakage of pressure from within the container.

The foregoing description of the invention is explanatory thereof and various changes in the size, shape and materials, as well as in the details of the illustrated construction, may be made, within the scope of the appended claims, without departing from the spirit of the invention.

What I claim and desire to secure by Letters Patent is:

1. A container including, a, container body having an opening in one of its walls, the opening being adapted to receive an element having frictional fastening means, the portion of the wall surrounding said opening providing overhanging means for sustaining the frictional fastening means of the element when the latter is inserted through the opening, and means for closing said opening against communication with the interior of the container and the contents'thereof.

2. A container as set forth in claim 1 wherein the closing means includes a frangible seal adapted to be ruptured by the insertion and connection of the element.
